Our health testing levels for the Brazilian Terrier
We group breeding programs into three levels based on testing depth. Ask your breeder directly which level they meet.
A breeder at the Great level performs all mandatory tests plus 4 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Apple head
Allgemeine Fitness und Anatomie
Apfelkopf, or apple head, describes an extremely rounded, dome-like skull shape with a very pronounced forehead angle, or stop. This skeletal variation affects the structure of the head and can predispose dogs to open fontanelles, which are soft spots where the skull bones fail to close fully. In some cases, this shape can also restrict fluid flow in the brain, leading to a buildup of fluid known as hydrocephalus.
Physisch · Passing: {"resultNotOk": "Disease present"}
Malignant Hyperthermia(MH)
Stoffwechsel
Malignant hyperthermia, also known as Narkoseüberempfindlichkeit, is an inherited skeletal muscle disorder caused by a genetic mutation in the RYR1 gene. This mutation disrupts how calcium is regulated within the muscle cells, causing them to contract uncontrollably when triggered. These intense spasms generate a rapid, life-threatening rise in body temperature, typically brought on by specific anesthetic gases or extreme physical stress.
DNA · Passing: Clear
Cranioschisis
Zähne und Knochen
Lückenschädel is a congenital developmental defect affecting the skeletal system, specifically the skull. It occurs when the bones of the cranial vault fail to harden or ossify completely, leaving thin spots, depressions, or actual gaps in the bone structure. This defect is often associated with increased pressure within the skull and other brain abnormalities.
Roentgen · Passing: A
Mucopolysaccharidosis Type VII(MPS VII)
Mucopolysaccharidosis Type VII (MPS VII) is an inherited metabolic disorder belonging to a group called lysosomal storage diseases. It occurs when a deficiency in a specific enzyme prevents the body from breaking down complex sugar molecules, leading to a harmful buildup of waste products inside cells. This accumulation causes progressive damage to multiple organ systems, particularly the skeleton and connective tissues.
Passing: Clear/Carrier
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
